Effort

To create Project: uv init mcp world

To create and activate venv: uv venv .venv source .venv/bin/activate

To create MCP clients we will use MCP CLI: This will help with the below: 1. Build MCP clients that can connect to any MCP server 2. Create MCP servers that expose resources, prompts and tools 3. Use standard transports like stdio, SSE, and Streamable HTTP 4. Handle all MCP protocol messages and lifecycle events Use uv add "mcp[cli]" or uv add "mcp[cli]"

The FastMCP class uses Python type hints and docstrings to automatically generate tool definitions, making it easy to create and maintain MCP tools.

The MCP Host hosts an MCP client (Could be a streamlit app, fastAPI, Cursor IDE, Claude desktop or MCP inspector). This will listen to the MCP server which contains all the tools available. Stdio transport could be used if server and client sits in local. But SSE (Server sent events) is the way to host the server with tools in an endoint and build various clients to call that using SSE transport

To run the the client using mcp inspector: uv run mcp dev mcpworld/server/weather.py
